Interview Preparation Tips

Interview preparation tips for other job seekers - Worst experience ever. I've interviewed for my first round, got shortlisted for managerial on next day. Later the HR told that I've got shortlisted for HR round but the CTC I asked is not in their budget so she'll check with her manager and then setup my HR round. After some days when I check with her , she said her manager approved for very less budget which is even less than my holding offer. So she won't be able to process my candidature. While screening I told her my expectation and holding offer. She agreed to it and called me repeatedly to schedule for the interview within short span. I spent time and effort on these interviews, later it's for nothing. I had to cancel other interviews which was scheduled because this HR said I'm shortlisted for HR round. I've lost all other opportunities. Never ever do this to any candidate. Respect their time and effort they invest in your company. Clearly it shows how much the company values people or employee.
